Floribunda rose plant named `JACyelsh`

Abstract

A new and distinct variety of rose plant of the floribunda class, having a vigorous, upright habit of growth; resistance to powdery mildew and rust; its dark green, glossy, leathery foliage; continuous blooming during the growing season; and ease of propagation from softwood cuttings.

Description

The present invention relates to a new and distinct variety of rose plant of the floribunda class which was originated by me by crossing two unnamed seedlings.

The primary objective of this breeding was to produce a new rose variety having the bright yellow flowers and healthy, glossy, dark green foliage of the unnamed yellow floribunda seedling female parent combined with the bright yellow flowers, glossy foliage and tall, vigorous growth habit of the unnamed yellow shrub male parent. The objective was substantially achieved, along with other desirable improvements, as evidenced by the following unique combination of characteristics that are outstanding in the new variety and that distinguish it from its parents, as well as from all other varieties of which I am aware:

1. Vigorous, upright habit of growth;

2. Resistance to powdery mildew and rust;

3. Dark green, glossy, leathery foliage;

4. Continuous blooms during the growing season; and

5. Ease of propagation from softwood cuttings.

Asexual reproduction of this new variety by softwood and hardwood cuttings, as performed at Wasco, Calif., shows that the foregoing and all other characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

The accompanying illustration shows typical specimens of the vegetative growth and flowers of this new variety in different stages of development, depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

The following is a detailed description of my new rose cultivar with color descriptions using terminology in accordance with The Royal Horticultural Society (London) Colour Chart, except where ordinary dictionary significance of color is indicated.
